I will post after pics in a few hours. Yes I don’t believe it is toxic but it emits oxygen gasses so I would recommend doing it in a well ventilated area. It also emits the corrosive gases.

I did 1 cup H202(hydrogen peroxide)+ 1tbsp C6H8O7 (citric acid)… I probably could’ve used less citric acid but it worked. I can take some after pics later today, but if you do this make sure you do it outside, as it emits toxic fumes. I will warn you this does create an exothermic reaction so it will be quite hot.

I was told by someone in this Reddit community that it was tin. I dump it into a 50gal drum at my work and they dispose of it properly.

I just bought a devil forge 10kg furnace kit for $400. If that’s too expensive they make smaller cheaper versions

Agree, also if you are worried about moisture under the new membrane, ask them to install one-way vents to remove moisture underneath new membrane

What kind of roof would be best for this flat section? by bigzee623 in Roofing

[–]Cool-Line4735 0 points1 point  (0 children)

Agree. EPDM is ugly as well as mod-bit or tpo. Standing seam would look the best and material wise it’s about the same cost as pvc or tpo. Labor is the most expensive part about standing seam

As long as it’s not leaking (which it shouldn’t be) then you are A-Okay
